The "Meeting on Fundamental Cosmology, Santander 2015" follows previous conferences in Valencia (June 2013) and Fuerteventura (June 2014), and aims to provide a framework for discussing and exchanging ideas among the Spanish community of Physical Cosmology.

This conference gives the opportunity to review observational and theoretical progress and instrumental developments, paying special attention to current and future large-scale structure surveys and cosmic microwave background experiments, on which the Spanish community has an important participation.

During the meeting, we will review different aspects of particular interest in cosmology: latest results and news from Planck and other CMB polarization experiments, the physics of recombination and the distortions of the CMB spectrum, the status of SKA and the prospects for understanding the cosmic dawn and the reionization of the universe, the detection of dark matter, the latest constraints on neutrino physics, and probing inflation through primordial non-Gaussianity.

In this third edition of the meeting, young researchers (Phd students and postdocs) are particularly encouraged to ask for oral contributions, since a large fraction of the talks will be allocated for them.
